1 . It's no secret that exercising will improve your health. Working out on a regular basis is good for your body.But,did you know that living the fitness lifestyle will improve your brain power and make you a more productive person?

●Exercising helps you handle stress better.

When you work out regularly, your body simply functions better and you are healthier and less likely to suffer painful physical condition.    1    

●.Exercising gives you more brain cells.

According to the process of neurogenesis (神经发生), the rate at which your brain cells are growing will decrease as you get older.    2     In 2008, a study showed the brain cells of the people who exercise on a regular basis have a higher brain growth rate. Meaning, adults who don't ignore the gym have more brain power than those who choose to be inactive.

●.Exercising makes you happier.

When you do intense exercises, it releases a huge amount of endorphins (内啡肽) into your body. Did you know, a study from Duke University showed that depressed adults who started to exercise had the same positive results as those who took medieine? This is why endorphins are known as natural cure f depression.    3     Endorphins improve your abilities to prioritize tasks.This helps you stay focus o urgent matters on the workplace.

Your memory works better when you are active. The American College of Sports Medicine published a study that proves this.     5    Then, one part of the group was asked to go running, and lift weights while the other part of the group was asked to stay put. When the students were tested on their memories, it turned out that the group who went exercising scored much better than the other one.

2 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.

Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular （心血管的）fitness in middle age could delay or even prevent them from developing dementia. "

For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.

A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.

These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.

"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.
